Why cleaning solar panels is important
Why clean my Solar Panels?
Solar panels work by allowing light into the solar cells, the more light that gets in the more power it will generate, the panels are normally installed at an angle to make them more efficient, this does however make them prone to a build up of dust and dirt that does not clean itself with just rain, then if you take into consideration other elements like bird droppings etc this can have an extremely detrimental effect on the returns you are expecting from your own PV system.
The figures you have been given by your own solar installer are based upon your system working to its optimum performance when clean, this does not factor in any issues with the elements hence it is very important to have system cleaned and checked regularly. This will make sure you are getting the most from your system and most importantly you are receiving the correct ROI from the government feed in tariff
It has been proven that you can be losing between 20-40% of your generation by not cleaning your solar panel system in a normal residential area, in a dusty commercial type premises you can lose even more where a 60% reduction in performance has been lost due to conditions affecting the system.
